(Washington Post) – The explanation that Rep. Trent Franks gave in announcing his resignation this week centered on a House Ethics Committee investigation that he said was prompted by his discussions of surrogacy with two female subordinates. His statement turned a spotlight on the often medically complex world of infertility treatment, which many abortion opponents also consider ethically fraught. And the glare could intensify, with a former staff member alleging that the Arizona Republican offered her $5 million if she would bear his child.
